Smoke test article Federal guidelines suggest minimum daily amounts for vitamins and key minerals. However, unless you need to increase your intake for specific ones because of a deficiency or other medical reason, following so many numbers can be confusing. The best approach to ensure you get a variety of vitamins and minerals, and in the proper amounts, is to adopt a broad healthy diet. This involves an emphasis on fruits and vegetables, whole grains, beans and legumes, low-fat protein, and dairy products. The good news is that many common foods contain multiple mineral and vitamin sources, so it is easy to meet your daily needs from everyday meals.
